 1. Determine based on what you already know about the user's project or by asking them which of the following services is appropriate.
 2. Use the Firebase \`read_resources\` tool to load the guide to setup the product you choose.
 
-## Available Services
+The user will likely need to setup Firestore, Authentication, and Hosting. Read the following guides in order. Do not run the app until you have completed all 3 guides.
+ 1. [Firestore](firebase://guides/init/firestore): read this to setup Firestore database
+ 2. [Authentication](firebase://guides/init/auth): read this to setup Firebase Authentication to support multi-user apps
+ 3. [Hosting](firebase://guides/init/hosting): read this if the user would like to deploy to Firebase Hosting
+
+**firebase.json**
+The firebase.json file is used to deploy assets with the Firebase CLI. It contains configuration for firestore, hosting, and functions.
 
-- [Firestore](firebase://guides/init/firestore): read this if the user needs offline data or a mix of querying and realtime capabilities
-- [Realtime Database](firebase://guides/init/rtdb): read this if the user is building a "multiplayer" app or game such as a collaborative whiteboard
-- [Data Connect - PostgreSQL](firebase://guides/init/data-connect): read this if the user needs robust relational querying capabilities or expressly indicates interest in a SQL database
+Here is an example firebase.json file with all 3 services. Note that you do not need entries for services that the user isn't using. Do not remove sections from the user's firebase.json unless the user gives explicit permission. For more information, refer to [firebase.json file documentation](https://firebase.google.com/docs/cli/#the_firebasejson_file)

+- **Verification**: Guide developers to verify database creation at the [Firebase Console](https://console.firebase.google.com/) by clicking on the "Firestore Database" tab in the left navigation to confirm the database is created.
+- **Testing**: Recommend developers test their application and verify data appears correctly in the console. Ask developers to confirm they can see their test data in the console before proceeding to the next step.
+- **Security**: Recommend implementing authentication if the application handles sensitive user data. Guide users to navigate to the "Firestore Database" section and click on the "Rules" tab to view and configure their security rules.
+- **Security Warning**: Alert developers against making Firestore security rules public (allowing read/write without authentication)
